Product details
VKEFOT TB type 43x57x9 mm radial rotary shaft oil seal manufactured in Xingtai, China. TB is a classic flanged metal skeleton oil seal defined by ISO Type5 standard. The flanged carbon steel outer shell provides axial positioning and high rigidity, resisting deformation during assembly and vehicle operation.
This TB seal adopts spring-energized primary sealing lip plus built-in dust lip. NBR nitrile rubber delivers stable sealing against mineral oil and bearing grease. The dust lip effectively blocks mud, sand and splash water from entering the bearing cavity, ideal for dusty and wet working environments. Max working pressure ≤0.05MPa, allowable shaft speed up to 12m/s, operating temperature -35℃ to +100℃. Widely used for automotive rotary shaft overhaul, aftermarket replacement for vehicle shaft sealing and light machinery maintenance.
Key Features
- TB ISO Type5 flanged metal shell radial shaft oil seal, dimension 43×57×9 mm
- Rigid AISI1010 carbon steel flange housing, good anti-deformation property
- Spring loaded main lip + integrated dust lip, waterproof and mudproof
- NBR nitrile rubber, compatible with mineral oils and lubricating greases
- Aftermarket replacement for automotive rotary shaft sealing applications
Material & Working Condition
Base rubber material is NBR (Nitrile Butadiene Rubber). Compatible with mineral oils and greases. Not suitable for ester oils, brake fluid and strong chemical solvents. Confirm lubricant type and operating temperature in your RFQ.
Typical Applications
Automotive rotary shaft sealing, light machinery shaft sealing. This is an aftermarket replacement seal. Verify shaft diameter and housing bore dimension before purchase.
Installation Guide
- Clean shaft journal and housing bore thoroughly, remove old seal residue, rust, burrs and contaminants.
- Lightly lubricate sealing lip with compatible oil or grease before fitting.
- Press TB seal evenly and squarely into the bore until flange face fully sits against housing surface, avoid tilting.
- Prevent scratches or nicks on rubber lip during installation; lip damage will cause oil and grease leakage.
- After assembly, perform leak inspection before full load operation.
Packaging & Shipment
- Standard packing：neutral plastic bags + export cartons, packing quantity adjustable as requested.
Samples are available for standard stocked sizes; sample freight cost confirmed during RFQ.
